_satellite.cleanText

This function would trim leading and trailing whitespace from the string and replace any internal repeating whitespace characters with a single space " ".

Remedies:

1) For Data Elements in Launch, just check the Clean Text box on the configuration view.

2) If a function is needed, use the following:

//Adapted from https://github.com/adobe/reactor-turbine/blob/master/src/cleanText.js
function cleanText(str) {
return typeof str === 'string' ? str.replace(/\s+/g, ' ').trim() : str;
};
